Apple has patented a new AirPods sensor system that integrates active and reference electrodes into the housing and tips to measure brain activity and other biosignals[1]. The system can monitor electroencephalography (EEG), electromyography (EMG), and electrooculography (EOG) through electrodes placed around the outer ear[2].
The technology uses dynamic electrode selection, intelligently choosing specific electrodes based on user parameters and wearing conditions to optimize accuracy[2:1]. Users could potentially activate measurements through simple gestures like tapping the AirPods tip[2:2].
However, experts note significant challenges - current in-ear EEG systems require patient-specific 3D ear scans and careful cleaning procedures that may not align with Apple’s consumer product approach[3].



People own water filters and beds that don’t work when the Amazon servers go down.
People have subscriptions to improve their car’s acceleration or get seat warmers to work.
People voted for Trump and still think they did the right thing.
There are plenty of suckers who will buy these things.
